VGA计数，PSW2控制正逆计数，按下递减计数，弹起正向计数。利用VGA作为输出设备，显示计数值。-VGA count, PSW2 inverse control is counting? Reduced count, pop-up being counted. The use of VGA as the output equipment, revealed count.

SERDES资料，包括reliability_handbook,serdes_handbook,serdes_introduction(SERDES doc,include reliability_handbook,serdes_handbook,serdes_introduction)

BISS-B 源代码。包含传感器模式和寄存器模式(BISS-B source code. Includes sensor mode and register mode)

很多VHDL例子，没有测试，供大家参考-VHDL many examples, there is no test, for your reference

介绍了如何用vhdl语言实现处理器的spi接口-Describes how to use VHDL language processor spi interface

quartus一个完整的设计例子,从安装到实例完成，仿真等全过程，适合从0开始的初学者-Quartus a complete design examples, examples from installation to completion, the entire process of simulation, etc., suitable for the beginner to start from 0

在FPGA上编写的通过SPI总线配置外部DAC芯片DAC5686的程序，通过板级调试，验证可用。程序通过状态机实现，将需要配置的寄存器值转为SPI总线的数据格式发送出去。 (Configure external DAC chip DAC5686 via SPI bus program on FPGA written by board-level debugging, verification is available. Program through the state machine, you will need to configure the register values 椠渀琀漀 SPI bus data format sent.)

利用matlab设计了一个切比雪夫滤波器，并且对滤波器性能进行了仿真分析。(Using the matlab design a chebyshev filter, and has carried on the simulation analysis on filter performance. )

说明：  在MATLAB下自编实现快速傅里叶分析，(Fast fft own procedures, faster than the system call fft slowe)
